The light color is a specification of the color appearance of a light source and is measured in kelvin (k). The lower the kelvin value, the warmer the light; the higher the value, the cooler the light. Light sources of 3400K and above are considered ''warm'', while light sources between 3400 and 5700K are considered ''cold''. Light sources above 5700K are referred to as ''daylight white'' sources.

The Tresco by Rev-A-Shelf 120VDC Pockit 1W LED Lights are a great alternative to traditional bulb ceiling lights. The Pockit LED lights are energy efficient, producing just as much light as regular blub lighting at just 1 watt per light. The secret is the LED 1 watt chip that is rated for 25,000 hours of use before it is easily replaced. The LED lights are available in 2700k or 4200k color temperatures and require no minimum height above surfaces, as LED heat isn't radiated off the surface of the lights and is absorbed by the metal surroundings making them extremely safe to use no matter how long the lights are on. The lights can be recess mounted or surface mounted and are available with five finishes: White, Black, Chrome, Antique Brass and Nickel.
